Looking at getting new irons

[King Cobra II]

I think I'm goning to start looking for irons, and i'll probably buy them in the winter, or when ever they go on sale. I currently have my dads old King Cobra II's (about 7 years old or so). I'm an okay golfer, usually in the mid to high 80's, but haven't been playing to long. I'm gonna look to spend 4-600. I was thinking of getting Big Bertha's what do you guys think/suggest?

OK I am by no means an equipment expert or even close, so take this with a grain of salt. I would say for a 16 handicap, that the Big Berthas may not be for you. They are Callaway's "game improvement" iron, and are designed with a big, heavy, clunky bottom of the club designed to consistently get the ball WAYY up in the air. I have the Big Bertha sand wedge and I really like it, it is my go-to chipping/pitching wedge, but whenever I am in a hard lie I get nervous due to its thick design. Having said that I think that you could still probably use them well, but may not be able to work the ball as well as you want at your level.

I think for you the Callaway X-20 irons may be the better option if your looking to stay with Callaway, but they'll probably go past what you're looking to spend. That is why I didn't get them. I ended up with the Cobra FP irons, and I would recommend them. I think the price is very fair on them, and I feel they will grow with my game better then the BB's would.

hmm thats good to know, and something to defintly consider. I haven't been golfing to to long, and these cobras aren't to bad. I'm 16 years old and will be jr. this year, my senior year there moving golf to the fall(I can't playing spring do to baseball), so perhaps i'll wait untill next summer right before golf season and see where my handicap's at. BTW i've looked at some of the new cobras and i'd def consider that too.
EDIT: what are some irons i might look to get that i would "grow into", I think with regular play this summer/fall, and next i will drop my handicap and be around a 13-11. So what are some irons that i could probably hit with my current game, but as i progress could hit the clubs like there meant to be hit. all help is appreciated :)

You and I are in somewhat of the same boat. 18 handicap here and looking for that next step in golf club sophistication (my word. Others might not agree).

I am considering -- and thus wondering whether any would be a fit for you -- Callaway X18 or X20, TaylorMade r7, Mizuno MX25, new Ping G10. . . And the big step I am thinking of is either the Titleist 755 or 775.

Others have thoughts on these clubs? I have read all the reviews on this site.
